Hi Amanda
can you try it in freeview? tksurfer has been deprecated for a while now

Thank you!
So the answer to the first question is that yes I can convert it back to a curvature file and that curvature file can be loaded as an overlay. So this must mean that the problem is with reading the .asc file rather than the file being corrupt?
Cheers,
Amanda

mris_convert -c lh.thickness.asc lh.white lh.thickness.mgz
should do the trick cheers Bruce On Mon, 15 Oct 2018, Worker, Amanda wrote:

How would I do that? mris_convert doesn't seem to take .asc as an input?

Not sure. Can you use mris_convert to convert the asc back to a curv file?

Hello,
I am trying to overlay a .asc file in either freeview or tksurfer, but so far having no luck.
As practice and to determine the right format, I am simply using lh.thickness, which I've converted to .asc using the following command:
% mris_convert -c lh.thickness lh.white lh.thickness.asc
I am trying to overlay this onto lh.pial for one subject, however I cannot load the file and I get the following error message:
% mri_read(): couldn't determine type of file /data/project/biobank/normative_modelling/DATA/03129b39-45a0-4491-9fdf-c70
62a631d19/surf/lh.thickne
ss.asc
surfer: couldn't load /data/project/biobank/normative_modelling/DATA/03129b39-45a0-4491-9fdf-c70
62a631d19/surf/lh.thickne
ss.asc.
If you were trying to load a functional volume, make sure you selected the right registration method, and if necessary, that the registration file exists. If you were trying to load a volume-encoded value file, make sure it has the same number of values as this surface does vertices (128970). sclv_read_from_volume: error in FunD_New
Interestingly, I can load the file as a curvature file, but then can't play around with the threshold.
Do you have any idea what I'm doing wrong? Any help would be
appreciated!
Thanks,
Amanda
